ExOne (XONE+5.3%) rebounds a bit from its 2-day drubbing after Stephens' Chris Godby defends the company. Godby asserts ExOne's decline gives investors a "compelling entry point," and that Q2 results (a point of concern after light 2013 guidance was issued) are nothing to be worried about. Stratasys (SSYS+2.3%) and Proto Labs (PRLB+2.2%) are also bouncing.
